I couldn't help but notice that when Shiho's mom picked her up and berated her in the car, it was all about her mom and how she felt, blaming Shiho for everything. That seemed selfish, self-absorbed, and shitty. That's not a parent. That's someone who wants to be completely in control. Gross!
And now that we're getting Miwa's background, as much as Shiho is being painted as the better match for Miwa, I hope we get Saeko's background so we can see why she is the way she is and understand her a little better.
